I would like to do this refactoring since I did a high level consumer a while ago. A few weeks ago I had opened KAFKA-949 Kafka on Yarn which I was also hoping to add to contribute. It's almost done. KAFKA-949 is paired with BIGTOP-989 which adds kafka 0.8 to the bigtop distribution. KAFKA-949 basically allows kafka brokers to be started up using sysvinit services and would ease some of the startup/configuration issues that newbies have when getting started with kafka. Ideally I would like to fold a number of kafka/bin/* commands into the kafka service. Andrew please let me know if would like to pick this up instead. Thanks!

We aren't deprecating anything. I just noticed that the Hadoop contrib package wasn't getting as much attention as it should. 2. Andrew or anyone--if there is anyone using the contrib package who would be willing to volunteer to kind of adopt it that would be great. I am happy to help in whatever way I can. The practical issue is that most of the committers are either using Camus or not using Hadoop at all so we just haven't been doing a good job of documenting, bug fixing, and supporting the contrib packages. 3. Ken, if you could document how to use Camus that would likely make it a lot more useful to people. I think most people would want a full-fledged ETL solution and would likely prefer Camus, but very few people are using Avro. -Jay On Fri, Aug 9, 2013 at 12:27 PM, Ken Goodhope <kengoodh...@gmail.com> wrote: > I just checked and that patch is in .8 branch.
